Chapter 5.2, Problem 2CP

Calculate w, and determine whether work is done by the system or on the system when 928 kJ of heat is released and $\Delta U=-1.47\times {10}^3\text{kJ}.$

$\begin{array}{l}\text{a)}\hfill \\ \omega \text{= -1}{\text{.36 × 10}}^{\text{6}}\text{ kJ, done by the system}\hfill \\ \text{b)}\hfill \\ \omega \text{= 1}{\text{.36 × 10}}^{\text{6}}\text{ kJ, done on the system}\hfill \\ \text{c)}\hfill \\ \omega \text{= -5}{\text{.4 × 10}}^{\text{2}}\text{ kJ, done by the system}\hfill \\ \text{d)}\hfill \\ \omega \text{= 2}{\text{.4 × 10}}^{\text{3}}\text{ kJ}\text{. done on the system}\hfill \\ \text{e)}\hfill \\ \omega \text{ =-2}{\text{.4 × 10}}^{\text{3}}\text{ kJ, done by the system}\hfill \end{array}$
